Gravitational collapse involving electric charge in the decoupling limit of the dilatonic Gauss--Bonnet gravity
Anna Nakonieczna, Łukasz Nakonieczny
The paper discusses a collapse of a self-interacting electrically charged scalar field in the decoupling limit of the dilatonic Gauss-Bonnet gravity. The emerging spacetimes were e…
Gravitational dynamics in the Higgs-dark matter sector toy model: the field theoretic perspective
Anna Nakonieczna, Łukasz Nakonieczny
The objective of the paper was to examine gravitational evolutions in the Higgs--dark matter sector toy model. The real part of the Higgs doublet was modelled by a neutral scalar.…
Two interacting scalars system in curved spacetime -- vacuum stability from the curved spacetime Effective Field Theory (cEFT) perspective
Zygmunt Lalak, Anna Nakonieczna, Łukasz Nakonieczny
In this article we investigated the influence of the gravity induced higher dimensional operators on the issue of vacuum stability in a model containing two interacting scalar fiel…
Black hole factory: a review of double-null formalism
Anna Nakonieczna, Łukasz Nakonieczny, Dong-han Yeom
In this review paper, we comprehensively summarize numerical applications of double-null formalism for studying dynamics within the theory of gravity. By using the double-null coor…
Black hole initial data by numerical integration of the parabolic-hyperbolic form of the constraints
Anna Nakonieczna, Łukasz Nakonieczny, István Rácz
The parabolic-hyperbolic form of the constraints is integrated numerically. The applied numerical stencil is order accurate (in the spatial directions) while 'time'-integr…
Dark matter cosmic string in the gravitational field of a black hole
Łukasz Nakonieczny, Anna Nakonieczna, Marek Rogatko
We examined analytically and proposed a numerical model of an Abelian Higgs dark matter vortex in the spacetime of a stationary axisymmetric Kerr black hole. In analytical calculat…
Static configurations and evolution of higher dimensional brane-dilaton black hole system
Anna Nakonieczna, Łukasz Nakonieczny, Rafał Moderski +1
Static configurations and a dynamical evolution of the system composed of a higher-dimensional spherically symmetric dilaton black hole and the Dirac-Goto-Nambu brane were investig…
Scalar field as an intrinsic time measure in coupled dynamical matter-geometry systems. II. Electrically charged gravitational collapse
Anna Nakonieczna, Dong-han Yeom
Investigating the dynamics of gravitational systems, especially in the regime of quantum gravity, poses a problem of measuring time during the evolution. One of the approaches to t…
Scalar field as an intrinsic time measure in coupled dynamical matter-geometry systems. I. Neutral gravitational collapse
Anna Nakonieczna, Dong-han Yeom
There does not exist a notion of time which could be transferred straightforwardly from classical to quantum gravity. For this reason, a method of time quantification which would b…
Scalar field as a time variable during gravitational evolution
Anna Nakonieczna, Jerzy Lewandowski
Using a scalar field as an intrinsic 'clock' while investigating the dynamics of gravitational systems has been successfully pursued in various researches on the border between cla…
Dark sector impact on gravitational collapse of an electrically charged scalar field
Anna Nakonieczna, Marek Rogatko, Łukasz Nakonieczny
Dark matter and dark energy are dominating components of the Universe. Their presence affects the course and results of processes, which are driven by the gravitational interaction…
Phantom collapse of electrically charged scalar field in dilaton gravity
Anna Nakonieczna, Marek Rogatko
Our research focus on gravitational collapse of electrically charged scalar field in dilaton gravity and in the presence of phantom coupling. We examine dynamical behaviour of the…
Dilatons and the Dynamical Collapse of Charged Scalar Field
Anna Nakonieczna, Marek Rogatko
We studied the influence of dilaton field on the dynamical collapse of a charged scalar one. Different values of the initial amplitude of dilaton field as well as the altered value…
Dynamical Collapse of Charged Scalar Field in Phantom Gravity
Anna Nakonieczna, Marek Rogatko, Rafal Moderski
We investigated the problem of the dynamical collapse of a self-gravitating complex charged scalar field in Einstein-Maxwell-dilaton theory with a phantom copuling for the adequate…
